This study aimed to evaluate the influence of different levels of inorganic fertilizer and plant growth regulator on seed yield of radish (Raphanus sativus L.) was formulated and conducted during the rabi season of 2022-23 at vegetable seed production plot, Department of Horticulture (Vegetable & Floriculture), BAC, Sabour Bhagalpur. The experiment was conducted to determine seed production ability at four levels of fertilizers viz, (F₀-control, F₁-N40:P30:K40, F₂-N60:P40:K50,& F₃-N8P50:K50) as well as seven levels of PGRs viz, P₀ (Control), P₁ (GA₃ @ 50ppm), P₂ (GA₃ @100 ppm), P₃ (GA₃ @ 150 ppm), P₄ (NAA @ 50 ppm), P₅ (NAA @ 100 ppm) and P₆ (NAA @ 150 ppm). Inorganic fertilizers were applied at 20 days and PGRs as foliar spray at 30 and 60 days after stecklings transplanting. The experiment was conducted in RBD (Factorial) and replicated thrice. the combined effect of inorganic fertilizers and Plant growth regulators F₂P₃ significantly gave maximum diameter of pod (7.64 mm), length of pod (56.61mm), number of seeds/pod (6.18), 1000- seed weight (15.12g) and seed yield (18.23q/ha) and plant height is non significant. The treatment combination F₃P₆ gave the maximum number of branches (8.06). Hence, F₂P₃ treatment combination is a best combination for seed yield of radish and enhancing seed yield is our ultimate goal. As we performed the study in a particular location, we recommend multilocation trials in different agro-climatic regions to study and final confirmation of the results.
